I was doing some research into making API calls to Twitter using JavaScript. The one problem I ran into was calling remote domains. One quick solution I found was to use the Google Feed API. Google provides a really easy and simple interface for accessing feeds via JavaScript.
A quick how to:
To start out you must import the api using your Google API key.
<script src="http://www.google.com/jsapi?key=[Your Google API Key]"></script>This is script was taking from the Google AJAX API Playground, I just added in the call for Twitter, the full script is below.
First the Google feed object is instantiated with the call to the Twitter API via RSS.
var feed = new google.feeds.Feed("http://twitter.com/statuses/user_timeline/ianlintner.rss");The Google feed API is great way to access and work with remote feeds, and APIs using just JavaScript. This also an asynchronous call, so it should play well with other AJAX solutions.
The full listing, with my changes.
